9 . Similar to <? , except that the colors of the abdomen are less dis- 

 tinct, and the last segment of the abdomen is tufted with dense whitish 

 hairs, somewhat as in E. egle 9 .

HAD. Owen's Valley, California. Described from one cf and 9 in 

 good preservation. In the form of the wings and general structure of the 

 body, this species closely resembles E. egle and E. oregonensis, but the wings 

 are narrower than in E. collaris. The color of the abdomen separates it 

 readily from its allies found in the United States, though there is a very 

 similar Mexican species with a rosy head.
